<div class="intro">
    <p>This example shows how to populate a DataTable with data from the Yahoo! Local webservice retrieved via a same-domain script. First we create a DataSource.IO instance pointing to data, then using the DataTableDataSource plugin we can load data for Chinese restaurants near our office.</p>

    <p>In this example, we set the `initialRequest` value in the DataTableDataSource plugin constructor so that the initial data is loaded first and then the DataTable is rendered in a separate call.</p>

    <p><strong>Note:</strong> XML parsing currently has known issues on the Android WebKit browser.

<h2>Populating Your DataTable with Remote Data using DataSource.IO</h2>

<body class="yui3-skin-sam"> {{>need-skin-comment}}
```
<p>Your table can be easily populated with XML data from your back-end by creating a DataSource instance and using the DataTableDataSource plugin to load the data into a DataTable.</p>

<p>Start with the `use()` statement:</p>

```
YUI().use("datasource-io", "datasource-xmlschema", "datatable-datasource", function(Y) {
});
```

<p>Next create a DataSource.IO instance pointing to your data. (Note that in order to point the Yahoo! Local webservice, you would need to bypass cross-domain browser restrictions on XHR by creating a locally served proxy. You do not need to implement such a proxy when your data is accessed from the same domain.) Define the correct schema for the DataSourceJSONSchema plugin. This is a good time to call `sendRequest` to make sure the data returns as expected.</p>

```
var dataSource = new Y.DataSource.IO({
    source:"ylocal_proxy.php?zip=94089&query=chinese"
});

dataSource.plug(Y.Plugin.DataSourceXMLSchema, {
    schema: {
        resultListLocator: "Result",
        resultFields: [
            {key:"Title", locator:"*[local-name() ='Title']"},
            {key:"Phone", locator:"*[local-name() ='Phone']"},
            {key:"Rating", locator:"*[local-name()='Rating']/*[local-name()='AverageRating']"}
        ]
    }
});

dataSource.sendRequest({
    callback: {
        success: function (e) {
            Y.log(e);
        }
    }
});

```

<p>Now that the DataSource is created properly, define the columns that you want your table to show. These columns map directly to the parameter names returned in the data.</p>

<p>Now you are ready to create a DataTable using the columns you have defined. When you plug the instance with the DataTableDataSource plugin, point to your DataSource instance, and set an `initialRequest` value so that the initial data loads right way. Then call `render()` after the data response has been processed.</p>

```
var dataSource = new Y.DataSource.IO({
    source:"ylocal_proxy.php?zip=94089&query=chinese"
});

dataSource.plug(Y.Plugin.DataSourceXMLSchema, {
    schema: {
        resultListLocator: "Result",
        resultFields: [
            {key:"Title", locator:"*[local-name() ='Title']"},
            {key:"Phone", locator:"*[local-name() ='Phone']"},
            {key:"Rating", locator:"*[local-name()='Rating']/*[local-name()='AverageRating']"}
        ]
    }
});

var table = new Y.DataTable({
    columns: ["Title", "Phone", "Rating"],
    summary: "Chinese restaurants near 98089",
    caption: "Table with XML data from same-domain script"
});
table.plug(Y.Plugin.DataTableDataSource, {
    datasource: dataSource,
    initialRequest: ""
});

dataSource.after("response", function() {
    table.render("#pizza")}
);

```

<p>One final change you can make is to split the URL between the DataSource `source` value and the `request` value sent to the DataTableDataSource plugin. Splitting the URL this way facilitates making future requests to the same DataSource.

<p>Here's the code to run the whole example:</p>

```
YUI().use("datasource-io", "datasource-xmlschema", "datatable-datasource", function(Y) {
    var dataSource = new Y.DataSource.IO({
        source: "ylocal_proxy.php?"
    });

    dataSource.plug(Y.Plugin.DataSourceXMLSchema, {
        schema: {
            resultListLocator: "Result",
            resultFields: [
                {key:"Title", locator:"*[local-name() ='Title']"},
                {key:"Phone", locator:"*[local-name() ='Phone']"},
                {key:"Rating", locator:"*[local-name()='Rating']/*[local-name()='AverageRating']"}
            ]
        }
    });

    var table = new Y.DataTable({
        columns: ["Title", "Phone", "Rating"],
        summary: "Chinese restaurants near 98089",
        caption: "Table with XML data from same-domain script"
    });

    table.plug(Y.Plugin.DataTableDataSource, {
        datasource: dataSource,
        initialRequest: "zip=94089&query=chinese"
    });

    dataSource.after("response", function() {
        table.render("#pizza")}
    );

    // Make another request later
    //table.datasource.load({request:"zip=94089&query=pizza"});
});

```
